[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1 to 2 The combined flashlight in this embodiment includes a tube body 1, a control switch 2 and a charging port 3, and the tube body 1 is provided with a combination mechanism.
[0020] In this embodiment, the control switch 2 is fixedly connected to the cylinder 1 and extends to the outside of the cylinder 1. The control switch 2 is a push-button switch. Pressing it once activates low-brightness lighting, and pressing it twice activates high-brightness lighting, which is convenient for users to adjust and control the brightness, making it easy for users to use.
[0021] The assembly includes two electrode blocks 4 fixedly connected to the cylinder body 1. A lithium battery 5, which is in contact with the electrode blocks 4, is inserted inside the cylinder body 1. An annular heat sink 6, which is in contact with the lithium battery 5, is fixedly installed inside the cylinder body 1. The size of the annular heat sink 6 is adapted to the lithium battery 5. The annular heat sink 6 is located outside the lithium battery 5. During the charging or use of the flashlight, the annular heat sink 6 transfers heat to the lithium battery 5, which facilitates heat dissipation and cooling of the lithium battery 5 and extends the service life of the lithium battery 5. The cylinder body 1 has several heat dissipation holes 101 corresponding to the positions of the annular heat sink 6. The number of heat dissipation holes 101 is evenly distributed. The annular heat sink 6 exchanges heat with the air outside the cylinder body 1 through the heat dissipation holes 101, which facilitates heat dissipation of the lithium battery 5 and facilitates the dissipation of heat into the air, thus protecting the lithium battery 5 and other components inside the cylinder body 1.
[0022] In addition, the bottom cover 7 is internally threaded to the cylinder body 1, and a sealing gasket 701 is fixedly connected to the outside of the bottom cover 7. The sealing gasket 701 fits tightly with the cylinder body 1, and the sealing gasket 701 increases the airtightness between the bottom cover 7 and the cylinder body 1, reducing the entry of dust and rainwater into the inside of the cylinder body 1. At the same time, it also makes it convenient for the user to unscrew the bottom cover 7 to check or replace the lithium battery 5, making it convenient for the user to maintain and use the flashlight. A connecting block 8 is fixedly connected to the top of the cylinder body 1, and a lamp head 9 is externally threaded to the connecting block 8.
[0023] Specifically, the lamp head 9 has a threaded hole inside, through which it is threadedly connected to the connecting block 8. This facilitates the connection between the lamp head 9 and the connecting block 8, making it easy for users to install and remove the lamp head 9, and also facilitates the replacement of the lamp head 9. This makes it convenient for users to maintain and repair the flashlight. The lamp head 9 has an internally fixed lamp bead 10, and a transparent lens 11 is provided on the top of the lamp head 9. The external thread of the lamp head 9 is connected to a limit ring 12, which allows users to rotate the limit ring 12 to replace the transparent lens 11, making it convenient for users to maintain and use the flashlight.
[0024] The beneficial effects of the above embodiments are as follows:
[0025] This modular flashlight optimizes its structure through a modular design, facilitating easy assembly and disassembly. It enhances the protection of the internal battery, extending its lifespan and allowing users to easily inspect it. This design addresses the problems associated with flashlights lacking battery protection structures, such as poor battery heat dissipation during use and charging, which can negatively impact battery lifespan and hinder battery removal and inspection, thus compromising user maintenance and maintenance.
[0026] The working principle of the above embodiments is as follows:
[0027] When this modular flashlight needs to be assembled, the lithium battery 5 is inserted into the inside of the body 1, so that the two poles of the lithium battery 5 are in contact with the electrode block 4. The bottom cover 7 is then threaded to the body 1 to fix the lithium battery 5 in place. Then, the lamp head 9 is threaded to the connecting block 8. During the charging or use of the flashlight, the annular heat sink 6 transfers heat to the lithium battery 5 and dissipates the heat to the outside air of the body 1 through the heat dissipation hole 101, reducing the impact of heat on the lithium battery 5. At the same time, the user can loosen the bottom cover 7 to disassemble and inspect the lithium battery 5, thereby facilitating the assembly and installation of the flashlight, increasing the protection of the internal battery, and making it easier for the user to disassemble and inspect the internal battery.
